The day is 15 April 2013; the place is Boston; the occasion is the annual marathon. As we all know, two radicalised Chechen immigrants, Dzhokhar (Alex Wolff) and Tamerlan Tsarnaev (Themo Melikidze), set off two bombs which killed three people and injured several hundred others, including 16 who lost limbs.
This film is a very workmanlike and respectful, almost documentary-style, account of the eve of the event, the bombing itself, and tracking down of the assailants in a tense five-day manhunt. Mark Wahlberg, reuniting with the director for the third film in a row, is Boston detective Tommy Saunders, a composite of several real people, while Kevin Bacon plays FBI Special Agent Richard DesLauriers.
For writer and director Peter Berg, following "Lone Survivor" and "Deep Water Horizon", "Patriots Day" can be seen as the third part of his unofficial Americans-in-crisis trilogy which probably play better for US audiences than overseas, but manage to combine information with entertainment.
This time round, the viewer cannot fail to be struck by the complexity and sophistication of modern-day surveillance and forensic technologies. If only these technologies could prevent terrorist incidents (without too much of a sacrifice of our privacy and freedoms) as well as find those who have just committed such an atrocity.
